The most-cited number in blogging advice — "aim for around 1,500 to 2,000 words" — isn't wrong exactly, but it's answering a more specific question than most people asking it realize. A 2026 study analyzing 100,000 ranking pages found raw word count correlates with search ranking at just 0.18, barely above statistical noise, while content depth — genuine topical completeness, not length — correlates at 0.62, a real and meaningful signal. Word count and depth are related but not the same thing, and conflating them is exactly what produces padded, artificially lengthened posts that perform worse than tighter, genuinely complete ones.
Why the Old "Longer Is Better" Advice Isn't Simply Wrong — It's Outdated
The famous long-content-ranks-better studies from the 2015–2020 era measured a real pattern, but the actual causal factor was topical completeness, not word count itself — in an era when most competing content was thin, a genuinely comprehensive 2,000-word guide was almost automatically more complete than the 300-word posts it was competing against. The search landscape's baseline content quality has risen substantially since then, and the mechanism has been reinforced directly: Google's May 2026 core update specifically and explicitly rewarded original, first-hand, non-commodity content while penalizing aggregator-style and padded filler content — meaning the update targeted exactly the "add more words to seem comprehensive" tactic that made the old length-based advice partially work in the first place. Length was always a proxy for depth; the proxy has gotten considerably less reliable as competing content has genuinely improved.
What Actually Varies Length by 9x: Search Intent
The same 2026 study found word count varies by roughly nine times depending purely on the intent behind the query — from around 380 words for navigational searches (someone looking for a specific, known destination) up to roughly 3,470 words for commercial-research queries (someone comparing options before a purchase decision). This is the real answer to "how long should my post be": it depends almost entirely on what the searcher actually needs from that specific type of content, not on a single target number that applies uniformly across every post type on your blog.
| Content Type | Typical Word Count Range |
|---|---|
| News update / quick answer | 300–600 |
| How-to guide | 1,000–2,000 |
| Listicle / roundup | 1,200–2,500 |
| Pillar guide (comprehensive hub content) | 2,500–4,500 |
These ranges are a planning starting point, not a target to hit exactly regardless of what the content actually needs — the same 2026 research that produced the intent-variation finding also found that padded content (a high length-to-depth ratio, meaning length added without proportional genuine information) ranked an average of 4.2 positions lower than appropriately-sized pages covering the same topic. Padding isn't neutral; it's actively counterproductive.
The Diminishing (and Reversing) Returns Most Advice Doesn't Mention
Ahrefs' own research adds a specific, counterintuitive wrinkle worth planning around: there's a real positive correlation between word count and backlinks earned, but only up to roughly 1,000 words — past that point, the correlation between additional length and additional backlinks turns negative. A similar pattern holds for organic traffic specifically, with a moderate positive correlation up to around 2,000 words that also reverses beyond that point. The practical read isn't "never write past 2,000 words" — pillar content and genuinely complex commercial-research topics legitimately need more, as the intent-based ranges above show — but it does mean that extending a post well past what its actual topic requires, in the hope that more length alone helps, tends to work against you rather than for you once you're past these rough thresholds.
Formatting for AI Citation Changes the Calculation Again
For posts aiming specifically at AI Overview or AI-search citation (relevant given the direct-answer formatting covered earlier in this series), the 2026 research found an optimal section length of roughly 280 to 420 words per section — short enough to function as a clean, extractable answer unit, long enough to be genuinely complete. One 2026 analysis makes the point sharply: a tight 900-word post structured as six extractable 40-to-60-word answers under clear, question-shaped subheadings can out-perform a 3,000-word essay for AI citation purposes specifically, because AI systems extract and cite discrete, well-bounded answers more reliably than they parse dense, undifferentiated prose. For genuinely comprehensive pillar content, the same body of research found a 3,000-to-5,000-word range tends to be the sweet spot for broader AI Overview citation eligibility — meaning the two formats (tight extractable posts vs. comprehensive pillar guides) both have a place, serving different intents rather than competing on the same length scale.
What This Doesn't Mean
None of this means word count is irrelevant or that you should ignore length entirely and write whatever feels right — the content-type ranges above are grounded in real intent-matching data, and undershooting them (a 400-word "how-to guide" that can't realistically cover its topic) is just as much a mismatch as padding a simple, navigational answer out to 2,000 unnecessary words. The actual skill this data points toward is matching length to intent and genuine topical completeness, in both directions — neither defaulting to a single "safe" word count for every post regardless of type, nor treating any specific number as inherently better than a shorter, tighter piece that fully answers its specific question.
Length-Planning Checklist
- Identify the search intent behind your specific post before drafting — navigational, informational, commercial-research, or transactional — and let that drive your target range, not a single blog-wide default
- Use the content-type ranges above as a planning starting point, adjusted for your specific topic's genuine complexity
- For posts targeting AI Overview citation, structure content in roughly 280–420 word sections under clear, question-shaped subheadings
- After drafting, review for padding: any sentence that only restates a point already made is a cut candidate, regardless of whether cutting it takes you under your target range
- For pillar/comprehensive content specifically, don't be afraid of the 2,500–4,500+ word range — this is where genuine length correlates with genuine depth, provided every section earns its place
- Never add length purely to hit a round target number if the topic has been genuinely, completely covered at a shorter length
Frequently Asked Questions
Is there a minimum word count Google requires to rank a page at all?
No official minimum exists, and short, genuinely complete content (a quick-answer or navigational post) can and does rank well at a few hundred words when that length matches the actual intent behind the search.
Should I combine several short posts into one longer pillar post?
Only if the combined topic genuinely warrants comprehensive treatment as a single resource — if the original posts serve genuinely distinct search intents, keeping them separate (and internally linked, per the framework covered earlier in this series) usually serves readers and search intent matching better than forcing an artificial merge.
How do I know if my post is "padded" versus appropriately thorough?
A practical test: read the draft back and flag any sentence or section that only restates a point already made elsewhere in the post without adding new information — if a section could be cut in half without losing any fact or step, it's likely padding rather than genuine depth.
Does this length guidance apply the same way to a listicle as a how-to guide?
Not exactly — a listicle's length scales more directly with the number of genuinely distinct items covered, while a how-to guide's length scales with the number of steps and the complexity of each one. Both should still avoid padding individual sections purely to inflate total word count.
With a clear sense of how long any given post should actually be, the next question is what to do with content you've already written — since a single well-researched post rarely needs to exist in only one format.
